Here are the planned civs of this mod. Feel free to discuss it.
HUMANS
We should have three divisions of humanity: the Edain, the Middle Men (peoples related to the Edain, but that haven't gone to Beleriand), and the Dark Men (the peoples that have served Morgoth or Sauron).
EDAIN
The Edain should be divided in the House of Hador - lead by Húrin (Aggressive, Organised) , Elendil (Wise, Seafaring) or Elessar (Expansive, Philosophical) - the House of Beör - lead by Hyarmendacil (protective, Seafaring), Beren (Wise, Creative) or Elros (Industrious, Expansive)- and the House of Haleth - lead by Haleth (Protective, Creative), Ar-Pharazôn (Agressive, Seafaring), and Castamir (Expansive, Seafaring).
MIDDLE MEN
The Middle Men should be dividedin the Éothéod - lead by Eorl (Aggressive, Industrious), Helm (Protective, Expansive) or Éomer (Aggressive, Wise) - and the Men of Rhovanion - lead by Bard (Financial, Creative) and Vidugavia (Agressive, Protective).
DARK MEN
The Dark Men shoul be the Haradrim - lead by Herumor (Aggressive, Financial), the Easterlings - lead by Ulfang (Aggressive, Creative), and the Dunlendings - lead by Freca (Expansive, Financial).
ELVES
The elves should be much more powerful than the Humans, but decay quickly with the past of the Ages. This could be done increasing the cost of their units in the later ages (so a elven unit in the first age might have the same cost of a human's one, but in the fourth age a elven unit should be much more expensive). We should divide them in the Sindar, the Avari and the Noldor:
NOLDOR
The Noldor should be divided in houses: the House of Fëanor - lead by Maedhros (Wise, Industrious), Caranthir (Aggressive, Expansive) or Celebrimbor (Industrious, Creative) - the House of Fingolfin - lead by Fingon (Organised, Wise), Turgon (Industrious, Protective) or Gil-Galad (Seafaring, Organised)- and the House of Finarfin -lead by Finrod (Protective, Wise), Orodreth (Expansive, Creative) or Galadriel (Philosophical, Wise).
SINDAR
The Sindar should be divided in: Nandor -lead by Denethor (Creative, Organised) - Falathrin -lead by Círdan (Seafaring, Financial) and Doriath - lead by Thingol (Protective, Philosophical) or Dior (Expansive, Organised).
AVARI
The Avari should be lead by Thranduil (Protective, Financial).
DWARVES
The dwarves should also decay, but much slower than the elves. We should divide the dwarves in the Longbeard Clan - Lead by Durin (Industrious, Philosophical) or Dáin (Industrious, Organised) - and the Firebeard and Broadbeam Clans - lead by Azaghâl (Industrious, Financial).
THE SHADOW
The Shadow rpresents the Enemy, the forces of Morgoth (Destructive, Aggressive) and Sauron (Destructive, Protective). They should be very different from all others: a unstoppable horde, completely focused on destroying all the enemies, and uncapable of winning the game in any other way.
About Isengard and the Hobbits (that you didn't notice), I think they should not be included. By The Shadow, I have wanted to mean all the evil; Saruman and the orcs of the mountains weren't under direct control of Morgoth/Sauron, but they were all consequences of Morgoth lies and corruption, and they helped Sauron during the War of the Ring. The Dark Men aren't evil by they alone (they were Sons of Ilúvatar), they only were corrupted by the Shadow, but in the end of the Third Age some made peace with the United Kingdom.
About the Hobbits, I don't think they are important enougth, and I'm thinking about making them units of the Humans.
About the Traits: I distributed them trying to don't repeat any pair of traits, so each leader is unique. The new traits are:
Destructive-> Combat II for all Melee and Archery units
Seafaring-> Navigation I for all sea units
Wise-> +50% Great People born rate and Wonder Production
